topographic map

A map that shows the contours of the land via a two-dimensional drawing with multitudes of contour lines showing changes in elevations.Each map has its own scale.The contour lines indicate a change in elevation by the scale amount. For example, each line might represent a 1-foot change in elevation. The distance between the lines can be computed by reference to the distance scale.For example,1 inch might equal 50 feet.Two contour lines that are 1 inch apart would indicate a grade of 1 foot over the course of 50 feet, which is very gentle. The closer the lines on the topographic map, the steeper the incline.

The C[F.sub.N] values were in agreement with the results seen in the contour mapping, where the lower indoor tracer concentration was found for the release source at 2-G.
Other improvements to PC-DMIS v3.5 include the capability to move all five axes of the coordinate measuring machine simultaneously, added support for continuous scanning simulation when using an SP600 probe, filters to select specific dimensions than an operator is looking for, and enhanced contour mapping capability.
Current yield map development uses surface or contour mapping techniques such as inverse-distance, nearest neighbor, local averaging or kriging.
